Jaywalking laws and penalties can vary from city to city, but in many cities, they would be very similar, as many municipalities and states base their definitions of jaywalking and establish penalties for it using the Uniform Vehicle Code. Often there are laws at the state level that prohibit jaywalking alongside muncipal ordinances that define it more specifically. One area of difference is that many cities define jaywalking broadly as crossing the street in areas not clearly indicated by crossing lines, i.e. at intersections. Others only define it as crossing the street at a signalled intersection without a signal. In any case, the penalty for jaywalking is almost always a relatively minor fine, and in practice, police in major cities often overlook all but the most flagrantly dangerous instances of the offense.
